Public Class Methods

new(source, node_id, location, flags, numerator, denominator) click to toggle source

Initialize a new RationalNode node.

# File prism/node.rb, line 15074
def initialize(source, node_id, location, flags, numerator, denominator)
  @source = source
  @node_id = node_id
  @location = location
  @flags = flags
  @numerator = numerator
  @denominator = denominator
end

type() click to toggle source

Return a symbol representation of this node type. See ‘Node::type`.

# File prism/node.rb, line 15157
def self.type
  :rational_node
end

Public Instance Methods

===(other) click to toggle source

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.

# File prism/node.rb, line 15163
def ===(other)
  other.is_a?(RationalNode) &&
    (flags === other.flags) &&
    (numerator === other.numerator) &&
    (denominator === other.denominator)
end

numeric() click to toggle source

Returns the value of the node as an IntegerNode or a FloatNode. This method is deprecated in favor of value or numerator/#denominator.

# File prism/node_ext.rb, line 120
def numeric
  deprecated("value", "numerator", "denominator")

  if denominator == 1
    IntegerNode.new(source, -1, location.chop, flags, numerator)
  else
    FloatNode.new(source, -1, location.chop, 0, numerator.to_f / denominator)
